Lovely plant that I greatly covet, but so, so difficult to raise from seed, which is my preferred method of gardening.....

these white trillium grow in abundence in ontario canada in the bush. I have had sucsess in transplanting some in my back garden which is protected by a cedar fence on the south side so they do not get direct sun. the only problem i have is collecting the seeds before the ants do.I watch for construction sites where the builders are clearing the bush and just plowing the trillums under and try to bring a couple home, we are not allowed to pick them here but are allowed to transplant them.

I think wnstarr mistook an similar speces for Trillium grandiflorum. I don't remember much about the other species that it is similar to Trillium grandiflorum but is less hardy and is native to the Western part of the United States. I have grown it for at least seven years. It is a very slow spreader for me, and the size of the plants differs depending on the amount of light received and whenever it will bloom or not the current season. Self sowing is unnoticing by me at all. So be careful of planting more aggressive plants around them. That includes Jack in the Puplit, Early Meadow rue, and Wild Ginger.

Aren't we lucky to live in the Pacific Northwest where Trillium grandiflorum is a native plant. It blooms early Spring and as the blossom ages it turns pink to almost a burgandy. It is spread by ants gathering the sticky seeds and taking them to their nest. It is the perfect medium for it to germinate. Find then in the woods with dappled sunlight highlighting the wonderful white blooms. Some locals call them "Wild Easterlilies" as they bloom around the time of Easter.

Wake Robin is usually the Trillium erectus... starts out yellow and changes to a deep burgundy/brown. Impressive! The more common white trillium are the grandiflorum.
